摘　　要：多点试验对10个油菜品种(含对照)的鉴定和筛选结果表明,产量在品种间、环境(地点)间存在极显著差异,并且还存在品种×地点交互作用。对照中油杂2号产量居第1位,H0302比对照减产2%,不显著,H0301和希望106比对照分别减产3.4%和3.5%,显著。除H0301外,其余品种均达到"双低"标准,其中希望106和H0304品质较优。沪油16、华油1087和希望106综合抗性相对较高;H0302和H0304与对照相比差异显著,为稳定性低的品种,而其余品种与对照相比未达到显著水平。产量性状和单产间简单相关分析和通径分析表明,单产与每角粒数之间呈极显著正相关,千粒重与单株有效角果数之间呈极显著负相关,产量性状对于单产的相对重要性依次为每角果粒数>单株有效角果数>千粒重。综合各项数据鉴定筛选出4个高产优质品种,分别为中油杂2号、H0302、H0301、希望106。The identification and selection of ten rape varieties were done in this research. The results indicated that there was significant difference in yield among the variation of genotype, environment （sites） and their interactions. The yield of Zhongyouza NO.2 （CK） ranked first in the average production per acre. The yield of H0302 was lower than that of CK by 2% ,no significant difference. There were significant difference between the yield of CK and H0301, also between CK and Xiwangl06, lower by 3.4% and 3.5%, respectively. Other varieties also had a significant lower yield. The results of quality analysis indicated that all the varieties were double-low varieties except H0301 ,Xiwang 106 and H0304 had superior quality. Huyou16, Huayou1087 and Xiwangl06 had higher comprehensive resistance. Correlation and path analysis indicated that the correlations between yield per haetare and number of seeds per pod was significant positive at 1% level, while the correlations between 1000-seed weight and number of effective pods per plant were significantly negative at 1% level. The order of yield traits that contribute most to the yield per hectare was as follows： number of seeds per pod 〉 number of effective pods per plant 〉1000-seed weight. Considering all the data collected, four varieties,Zhongyouza NO.2,H0302,H0301 and Xiwang106 were identified as high-yield and good-quality varieties.
